Retevis A3 vs Retevis HD2

The Retevis HD2 is the clear winner here. This isn't a close call despite the $100 price premium.

The most important differentiator is feature set. The HD2 includes DMR digital mode, APRS, and GPS functionality, making it genuinely useful for modern amateur radio activities. The A3 appears to be a basic analog-only radio with virtually no modern capabilities. The HD2's overall score of 69 versus the A3's 31 tells the real story.

The A3 makes sense only as an absolute budget starter radio if you want to spend minimal money and don't care about capabilities beyond basic FM simplex. The HD2 is the choice for anyone who plans to actually use their radio beyond casual experimentation, whether that's digital communications, location tracking, or APRS beaconing.

We recommend the Retevis HD2. At $180, you're getting a radio that will grow with your interest in the hobby. The missing TX power specs for both radios is concerning and should be clarified, but based on available information, the HD2's superior feature set and significantly higher score make it the only sensible choice for most buyers. The A3 price advantage disappears once you factor in real-world utility.
